Very cool interactive map: http://www.weparkway.ca/interactivemap/InteractiveMap.html
It will be the first major highway project in Ontario since the 407 and 416 were completed in the late 1990's.
They also extended Highway 417 west from Panmure Rd to Arnprior, which opened in 2004 (I think). But yes, there have been relatively few transportation infrastructure projects of any kind in Ontario in the past decade or so.
